Towards High-Throughput High-Frequency CMOS Nuclear Magnetic Resonance Spectroscopy

Book Description
Driven by the many of Nuclear Magnetic Resonance (NMR) spectroscopy applications, there is an ever-increasing demand for high-throughput NMR receivers to accelerate the speed and reduce the cost of the NMR spectroscopy. The envisaged solution by the industry is to employ significantly stronger static magnetic fields to achieve higher signal-to-noise ratio (SNR). However, this demands for the system to operate at proportionally-higher frequencies to satisfy the Larmor equation and to be able to shrink the receiver coil size (hence, fit higher number of parallel receivers in the same space) without the loss of SNR. Despite the benefits, a higher frequency of operation introduces several challenges in the design of the receiver's transducer (i.e., coil) and the readout circuitry (i.e., tuning, matching, and amplification circuits). We present the design and optimization of an electromagnetic Radio Frequency (RF) coil along with the readout circuitry both integrated on the same silicon-based platform for fabrication in a standard 0.35-m complementary metal-oxide-semiconductor (CMOS) technology. In the design of the coil, all the important electrical and physical parameters that could affect the NMR spectroscopy's overall performance are analytically identified and taken into account. Additionally, the readout integrated circuit is designed to be compatible with a wide range of on-chip and off-chip coils. The circuit architecture and the design procedure proposed for the readout circuit are adaptable to any frequency of operation. The presented integrated system consists of two channels enabling simultaneous NMR spectroscopy, and has no practical limitations for channel scaling. To the best of our knowledge, this design is the first CMOS-based NMR receiver operating at 500 MHz. While all components are designed and optimized for this frequency, the presented design procedures for both the coil and the readout circuits are applicable to higher frequencies.

Manufacturing Process Controls for the Industries of the Future
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309061849
Category : Technology & Engineering
Languages : en
Pages : 72
Book Description
Manufacturing process controls include all systems and software that exert control over production processes. Control systems include process sensors, data processing equipment, actuators, networks to connect equipment, and algorithms to relate process variables to product attributes. Since 1995, the U.S. Department of Energy Office of Industrial Technology 's (OIT) program management strategy has reflected its commitment to increasing and documenting the commercial impact of OIT programs. OIT's management strategy for research and development has been in transition from a "technology push" strategy to a "market pull" strategy based on the needs of seven energy-and waste-intensive industries-steel, forest products, glass, metal casting, aluminum, chemicals, and petroleum refining. These industries, designated as Industries of the Future (IOF), are the focus of OIT programs. In 1997, agriculture, specifically renewable bioproducts, was added to the IOF group. The National Research Council Panel on Manufacturing Process Controls is part of the Committee on Industrial Technology Assessments (CITA), which was established to evaluate the OIT program strategy, to provide guidance during the transition to the new IOF strategy, and to assess the effects of the change in program strategy on cross-cutting technology programs, that is, technologies applicable to several of the IOF industries. The panel was established to identify key processes and needs for improved manufacturing control technology, especially the needs common to several IOF industries; identify specific research opportunities for addressing these common industry needs; suggest criteria for identifying and prioritizing research and development (R&D) to improve manufacturing controls technologies; and recommend means for implementing advances in control technologies.
